What Armanino Does Well
Armanino LLP is a licensed independent CPA firm with over $400M in annual revenue, making it one of the larger independent accounting firms in the United States. Their practice spans audit, tax, consulting, business management, and risk assurance and advisory services.
Armanino's strength is enterprise-scale engagements: public company audits, large M&A transactions, complex tax structuring, and compliance at scale. They have the depth and breadth to handle engagements that require large teams and specialized expertise across multiple disciplines.
According to their website, their six departments provide traditional and non-traditional services, and they have the scale to deploy significant resources for large clients. For enterprise companies with complex compliance requirements, Armanino has the credentials and capacity to serve those needs.
The limitation is fit. Armanino's model and pricing are calibrated for enterprise engagements. For established businesses at $5M-$50M revenue, the Armanino engagement model is likely oversized—too much infrastructure, too little senior attention, and rate structures designed for larger clients.
What Sets Eagle Rock CFO Apart
Eagle Rock CFO is a boutique finance team—not a CPA firm—purpose-built for established businesses at $5M-$50M revenue. The team covers accounting/bookkeeping, controller oversight, treasury management, and CFO/FP&A strategy, all under one roof with dedicated senior attention.
The difference is focus and fit. Eagle Rock is not a full-service accounting firm with enterprise overhead. We are a focused finance team that works with a defined client base of established businesses, providing senior CFO-level attention that large firms cannot match at this revenue stage.
Eagle Rock CFOs are operators who have built and scaled companies. They bring real operational experience to every conversation. At our scale, every client gets senior attention—not a rotating team of associates working on your account.
For established businesses, the choice is between enterprise CPA firm infrastructure and a boutique finance team that is designed for your size. Eagle Rock is the latter.
Transparent pricing: Financial Analytics from $1,750/month, Full Fractional CFO from $3,500/month, Dedicated CFO Partnership from $7,000/month. Month-to-month with no lock-in.

Does Eagle Rock provide audit services like Armanino?
No. Eagle Rock is a finance function provider, not a CPA firm. We do not perform audit services. For audit needs, you would work with a CPA firm like Armanino. However, we can manage the financial operations that produce the data and schedules your auditors need, which often reduces audit complexity and cost.
What size business is Eagle Rock designed for?
Eagle Rock serves established businesses with $5M-$50M in annual revenue that need a complete, integrated finance function. At this stage, you need more than bookkeeping—you need a CFO partner with operational experience who can drive strategic decisions.
Does Eagle Rock work with businesses that have existing CPA firms?
Yes. Many of our clients have an existing CPA firm for tax and audit work while engaging Eagle Rock for their ongoing finance function. We integrate with your existing professional advisors rather than replacing them, and we coordinate with your CPA to ensure financial operations support their needs.
